ABSTRACT

Percutaneous coronary intervention with angioplasty and stenting is well established in the treatment of coronary artery disease. However, the many advances in technique and equipment over the last couple of decades have yet to significantly reduce the incidence of restenosis. This Achilles’ heel has necessitated frequent re-interventions and also introduced a new iatrogenic disease of in-stent restenosis. Brachytherapy and coated stents may be the answer to this difficult problem. Many papers have been published in the last few years on these two new modalities of treatment, and we review the evidence available so far. Early results show that brachytherapy significantly reduce the incidence of restenosis when used in restenotic lesions, and coated stents significantly reduce restenosis in de novo lesions. This early promise of brachytherapy and coated stents, if confirmed in longer-term studies, will represent a breakthrough in the battle against restenosis and may dramatically change the practice of interventional cardiology in the near future.


Since Andreas Gruntzig first demonstrated its use in humans in 1977, the utilisation of percutaneous transluminal coronary angioplasty (PTCA) has grown tremendously throughout the world today. The ability to treat coronary artery stenosis with this minimally invasive alternative to coronary artery bypass surgery is attractive to both cardiologists and patients alike.
